Detailed explanation-1: -Answer and Explanation: since electron is a negatively charged particle, the direction of force is opposite to the direction of Electric Field. Therefore, in the given situation: As soon as electron enters horizontally in a region of downward directed Electric Field, electron experiences an upward directed force.
Detailed explanation-2: -According to it, the force experienced will be in the south direction.
Detailed explanation-3: -Thus, an electron moving north will slow down and eventually reverse its direction if it enters an electric field that points north.
Detailed explanation-4: -2. An electron traveling north enters a region where the electric field is uniform and points north. The electron will then: Because the charge of the electron is negative, the force on it, F = qE is pointed backwards and the electorn will slow down.
Detailed explanation-5: -An electron will move in the opposite direction of the electric field because of its negative charge. Therefore it will move toward the left.
